SMOKING-PIPE CLEANER.

Specification of Letters Patent.

Application filed October 31, 1907. Serial No. l100,055.

pipes, and its object is to provide a cleaner` designed to remain in the pipe while the lat- 'ter is in use, and to be capable of manipulation in such manner as to remove any accumulation inthe pipe bowl or stem which it is desirable to remove.

The invention comprises a semi-tubular structure adapted to extend through the pipe bowl and into the stem with a continuation adapted to be passed through the pipe bowl and snugly rit the same diametrically oppo site the stem, the said continuation terminating in a finger hold of suitable shape, so that the attachment may be rotated on a longitudinal axis and also withdrawn from or inserted into the pipe, as the case may be.

The invention will be best understood by reference to the following detail description, taken in connection with the accompanying drawings forming part of this specification, in which drawings,

Figure 1 is alongitudinal section, with parts in elevation, of a pipe with the cleaner attachment in place. Fig. 2 is a section on the line :thx of Fig. l, looking toward the stem. Fig. 3 is a perspective view of the 'linger attachment on an enlarged scale.

Referring to the drawings, there is shown the bowl 1, stem 2, and a portion of the .mouthlpiece 3 of an ordinary pipe. These severa portions of the pipe are shown inl a more or less conventional manner, since the type or style of tobacco pipe is not at all material to my invention, because the invention is adapted for use with a great varietyvof types and styles of' tobacco pipes.

Inthe body of the bowl l opposite and in line with the bore of the stem 2, there is an orifice 4 for the reception of the attachment, as will presently appear.

The attachment comprises a cylindrical section 5 with a semi-tubular extension 6 on one side or the cylindrical section 5, and a ringer-hold 7 on the other side. drical portion 5 is of such size as to snugly iit the opening 4 in the pipe bowl, and the semicleaner imperative.

The cylintubular section 6 is of suiicient length to extend across the pipe bowl and into and nearly through the stem 2, while the ringen hold 7 is exterior to the pipe bowl. Now, when the attachment is inserted in a pipe, the open side of the tubular section 6 permits `free access of air, or free circulation, through the stem 2, whether this open side is placed uppermost or not. Now, let it be supposed that the pipe has been used for a considerable time and there is considerable choking of the bore oi?l the stem by accumulations of deleterious material, it is then only necessary to rotate the attachment upon its longitudinal axis two or three times when the edges of the semi-tubular section 6, which section should snugly fit the bore of the stem 2, will scrape oli any accumulations on the inside of the stem and cause them to be deposited in the interior of the said extension 6. Now, this section may be withdrawn with the scraped ofi material in it and then may be cleansed, and later reintroduced into the pipe. There is thereby provided not only a means for loosening accumulations, butfor collecting the same and for removing them from the pipestem and from the bowl of the pipe at practically one operation.

It is to be noted that the section 5 has been described as cylindrical. It is, in fact, slightly tapering so as to it snugly into the opening 4 and to bind therein when desired. It is not necessary to remove the structure from the pipe unless the stem becomes so choked as vto render the removal of the Usually, the simpler@- tation of the device is su'ilicient to open up the draft.

The end 7 is made globular and is perforated so that it may remain cool, but it may be otherwise constructed and may be made either plain or ornamental to beiit the type of pipe with which the attachment is used.

By the term semi-tubular, as applied to the section 6, it is not intended to mean that this section is strictly semi-tubular, for it may embrace an arc greater or less than 180o.. its exterior diameteris substantially that of the bore of the pipe stem, and it will then act to scrape away accumulations, since the edges will act as cutting edges.
